Alcolin NC120 is a superior quality siloxane liquid formulated to provide water repellency and preserve the original beauty of unpainted masonry surfaces. NC120 is distinguished for its excellent penetrating ability and extremely high alkaline resistance, which gives it an effective life of at least 10 years if correctly applied. NC120 preserves the original beauty of masonry by preventing water caused damage such as dirt penetration, efflorescence, moss growth and defacing of interior walls. NC120 penetrates deep into masonry and remains invisible when cured. As it is not a surface coating, it allows building materials to breathe normally. 5 Litres.
